Other claims from this paper (5)
- Association Photosynthesis in upper canopy trees decreased 28% during the extreme 2015 dry season relative to other 2015 seasons.
- Association Photosynthesis reduction under extreme drought and high temperature was related only to stomatal closure.
- Observation Photosynthesis reduction was not related to chlorophyll a fluorescence parameters, chlorophyll or leaf nutrient concentration.
- Observation Photosynthesis increased about two months after the stomatal-closure decrease, as rains returned.
- Observation The Central Amazon forest trees show a margin of resilience to one-off extreme climatic events.
